The Vegetation Observations Data Exchange Task Group is a subgroup of the [[][Observations and Specimen Records Interest Group]] and is seeking to construct an international exchange standard or schema for vegetation plot data that can be used by groups who are engaged in studies of vegetation community structure. A new schema is required because existing schemas such as Darwin Core v.2 and the ABCD standard only allow exchange of spatial and temporal occurrence information for individual specimens from biological collections and these are not adequate for community sampling because the information required goes beyond specimen occurrence data.
A new effort to develop a core semantic model for observational data in the ecological and environmental sciences is underway (TDWG Observations Task group). While this observational data model has much potential for unifying all observational data, it is still several years away. The creation of a VPS exchange schema (Veg-X) will provide the immediate opportunity to begin organizing vegetation data, and making them available to the entire ecological community. Veg-X will also hopefully assist in the developing observational ontology.

---++ %MAKETEXT{"Goals, Outputs, and Outcomes"}%
This Task Group plans to complete development of an international exchange standard for plot-based vegetation data that is accepted by the broader vegetation science community and endorsed by the International Association for Vegetation Science (IAVS) and TDWG. Our goal is to design a TDWG standard for vegetation plot data that is maximally compatible with existing standards and is useful for community-based co-occurrence sampling for many types of organisms (e.g., inter-tidal zone plots, sub-tidal benthic plots and transects).
Following the two workshops and several subsequent revisions, the schema will be made available for review on this site and will also be presented at the IAVS annual meeting June 2009. If necessary, additional revisions will be undertaken in time to present progress to the OSR groups workshop during the TDWG annual meeting 2009.
---++ %MAKETEXT{"History/Context"}%
Vegetation scientists from 22 countries attended the first International Association for Vegetation Science (IAVS) Ecoinformatics Working Group meeting in 2003, and unanimously endorsed the creation of an international exchange standard. The Governing Council of IAVS has invited TDWG to work with interested colleagues to develop a standard for approval and endorsement by IAVS.
Two workshops were held to discuss and develop a plot-based vegetation data exchange schema (April 2007, June 2008, at National Evolutionary Synthesis Center (NESCent) in Durham, NC). The first workshop of 12 participants from 6 countries formulated a common set of goals, concepts, and terminology for plot-based vegetation data. The second workshop was held with a smaller group, who developed this ontology into a draft XML schema representation for consideration by the broader community. This draft was presented at the OSR Interest group&#8217;s meeting at the annual TDWG meeting in Perth October 2008 and also at a workshop at the National Center for Ecological Analysis and Synthesis (NCEAS) held in December 2008: &#8220;Developing an integrated botanical information network to investigate the ecological impacts of global climate change on plant biodiversity&#8221;. An outcome from this workshop will be to develop proposals for the [[][iPlant collaborative]] (NSF funded Plant Science Cyberinfrastructure Collaborative program - PSCIC). At this meeting the draft schema was endorsed as a candidate, subject to modifications and acceptance as a TDWG standard, for use as the group&#8217;s common vegetation data exchange standard.
---++ %MAKETEXT{"Becoming Involved"}%
A draft schema has been through several iterations and is now reasonably stable. However, there are many improvements that could be made to the structure, contents, and documentation, and there is room for greater reuse and alignment of other ontologies with this draft. We welcome feedback through the TDWG Wiki and will also be eliciting comment from various active vegetation research groups on any and all aspects of the schema. We are particularly interested in ensuring that the schema sufficiently covers end-user needs, and in determining whether there are major logistical problems in fitting specific vegetation types to the data structure as defined by the schema. Contact any key member (* above) for details.

* Terrestrial and Freshwater Biodiversity Information Systems (TFBIS) programme, New Zealand (
* ARC-NZ network for Vegetation Function (, supported by Australian Research Council and Landcare Research NZ.
* International Technical Input Programme (ITIP), Foundation for Research, Science and Technology, New Zealand.
